Show Guide: 'Tree On A Hill'

Synopsis: Clive (Rhodri Meilir, My Family) and Margaret (Nia Roberts, Hidden) live a quiet life in the rural Welsh town of Penwyllt. It’s a gentle, chocolate-box-like place, but Clive is aware things are changing and cracks in the idyllic town are starting to show: the police are investigating mysterious fires in the countryside, and he can’t help but feel something darker could be going on. When Margaret’s sister and her husband Glyn (Richard Harrington, Silent Witness) go on holiday, Clive says he’ll cat sit. One night, Clive and Margaret sneak over to the house and drink like naughty teenagers. But when Glyn surprises them by coming home early, in her shock and unaware it is him, Margaret makes a split decision and smashes a bottle over his head, accidentally killing him. This one act turns their lives upside down and sets off a catalogue of disasters and curious happenings. (Courtesy, Britbox, 2025)
